Ubuntu 10.04 DomU Xen 4.0
Hi Everyone,
How does one install Ubuntu 10.04 DomU in PV mode when running Xen 4.0? My Dom0 is also running 10.04.
Can I still use the CD?
Thanks

RAM security
Hi Everyone,
In Xen, is a DomU able to access data in RAM which a previous DomU has stored in the past, but didn''t "zero" it?
I understand that this is a problem with physical disks (using phy:/), just wondering if the same stands with RAM
Thanks

HVM Network Interfaces
Hi Everyone,
In my HVM guest''s config file, I have given my guest 3 interface. I have
called them fw1, fw2 and fw3. I have joined each interface to a bridge
on the Dom0. This does appear when I do a "brctl show". However, there
are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where
x is the domain ID for the guest). Furthermore, I am only able to run

Promiscuous mode
Hi Everyone,
In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created?
# Accept packets leaving the bridge going to the domU only if
# the destination IP for that packet matches an authorized IPv4
# address for that domU.
iptables -A FORWARD -m physdev --physdev-out vif1.0 \
--destination 216.146.46.43 -j ACCEPT

/dev/hvc0: No such file or directory
Hi Everyone,
In the guest image I download from stacklet, a Ubuntu 10.04 x86_64 DomU,
in /var/log/auth.log, I see:
/dev/hvc0: No such file or directory
listed a lot of times. I''m not experiencing any problems, however it
makes looking through logs for auditing purposes a bit annoying.
Any ideas what this is? I think it has something to do with the

VT-x not found..
Hi Everyone,
I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide:
http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/
Now, using the new kernel that it gave me, the system doesn''t seem to be
able to detect vt-x..
In virt-manager, Local Install Media and Network Boot are greyed out..
Any ideas?
Thanks

Convert HVM to PV
Hi Everyone,
To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter?
Or is there something else I am missing?
Thanks

Install ubunto domU
Dear *,
I''m more used to work with RedHat like OSes. Still, I did not denied the
request from a user who wants a domU based on ubunto. I usually use
virt-install to do the job, with a script similar to this one:
#!/bin/sh
BASE=SL-4.7-i386-pv \
virt-install --nographics \
--nonsparse \
--paravirt \

Dell OpenManage
Hi Everyone,
I have a Xen host (Xen 3.4.2) which is running CentOS 5.5 Dom0. I wish to install Dell OpenManage to get a nice web interface with hardware status.
Do I need to do anything special to get this working on a Xen host? Or does it work out of the box? The reason why I''m asking, instead of trying, is that my server is currently on its way to a colo, and I won''t have

ionice and blkback
Hi Everyone,
When you want to use ionice to limit the amount of disk a DomU has, due
to have to run ionice on every blkback process?
Incidently, what is the format of the blkback process? I see the
following in ps aux:
blkback.xx.xvda
blkback.xx.xvda1
blkback.xx.xvd
where xx appears to be the domain ID. I''m curious as to the last few
letters mean?
Thanks

iSCSI and LVM
Hi Everyone,
I am going to get a storage server which will be connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will have a 50% share of the RAID10 array, space wise).
What is the best way to go about this? Should I:
a) Split the RAID10 array into 2 partition on the

AW: debian Lenny -> Squeeze domU mdX software raidmigration - failed to assemble arrays
Hi,
to make transitions more convenient, I've done this by using uuid instead of device names.
If you ls -l /dev/disk/by-uuid inside your domU, you'll see something like

Lan connection interrupted on domU start
Dear List,
I use Debian Squeeze with Xen dom0 Kernel 2.6.32-5-xen-686,
the Xen Hypervisor 4.1 and qemu 4.0.
I have installed a HVM domU which contains
a Debian Squeeze standard installation.
Everytime I start the domU with the ''xm create ..'' command from dom0,
the eth0 lan connection gets interrupted and rebuilts.
When domU is booted, the dom0 system hangs every minute for

pfSense HVM
Hi Everyone,
Does anybody have any experience using pfSense on Xen? I would most
probably have to use HVM...
My idea would be to use PCI-Passthrough to the pfsense DomU, and only
make the Dom0 accessable via the pfsense firewall
Thanks

XCP: No Ethernet card was detected on Debian Squeeze domU install
Hello,
I am trying to setup Debian Squeeze as domU, but I get the message below
during the setup process:
No Ethernet card was detected on Debian Squeeze domU install
And it asks to select the driver to me.
I followed the instructions at page 27 of the guest.pdf manual, but there is no
indication on how to set-up the bridge in order to make the ethernet interface
